Authors:Xin Zhang, Liang PengPages: 161 - 175Abstract: With the evolution of technology systems, main parameters of value (MPV) show an S-curve development with time. This paper presents a general TRIZ-based S-curve analysis of the technology evolution of LED lights as well as the similarities and differences in the evolution of incandescent lamps, gas discharge lamps and LEDs. S-curve analysis is strategically meaningful in making technical development plans, and evolution laws will facilitate in predicting the future of LEDs. Understanding them will offer possibilities for tool-assisted problem solving.Keywords: S-curve; LED lights; evolutionary trendsCitation: International Journal of Arts and Technology, Vol. 10, No. 3 (2017) pp. 161 - 175PubDate: 2017-09-18T23:20:50-05:00DOI: 10.1504/IJART.2017.086654Issue No:Vol. 10, No. 3 (2017)

Authors:Katerina Antonaki, Eleni GlinouPages: 189 - 205Abstract: Our experience of the city is formed through a constant symbiosis with a vast amount of printed information. In this article, we illustrate the aural aspects of those printed information in the urban space. We do that by referring to current discourses around visual and sound theories and by engaging contemporary open source technologies/software. The text is part of a wider design-research project which is in progress and which investigates the aural qualities of the printed information of urban space and tries to 'translate' the so called visual noise of urban space into sound. The article is based on the conceptual end of designing an app which will translate the visual noise of urban space into sounds.Keywords: space perception; auditory perception; hybrid narrations; image and sound; urban soundscapes; visual noise; aural cartography; silent readers; visual identity; aural urban identity; aural dimension of images; city soundscapes; visual and aural stimulCitation: International Journal of Arts and Technology, Vol. 10, No. 3 (2017) pp. 189 - 205PubDate: 2017-09-18T23:20:50-05:00DOI: 10.1504/IJART.2017.086663Issue No:Vol. 10, No. 3 (2017)

Authors:Borut Batagelj, Franc SolinaPages: 206 - 230Abstract: In contemporary digital art computer technology plays an integral part not only in the creation of art pieces but also in their functioning as artworks. Such digital artworks have usually a performative or interactive character and therefore rely on an underlying working computer system. Since computer technology advances with such unrelenting pace, hardware and software modules eventually become obsolete. How to preserve digital art works in these circumstances from an art preservation standpoint is much debated. In this article we discuss issues in the preservation of digital art works using as a case study a 15 years old interactive art installation '15 seconds of fame'. The art installation could be maintained in a good working order first just by small changes, reacting mainly to new versions of operating systems. After more then ten years a complete rewrite of the code was necessary to move it to a new computing platform.Keywords: digital art; born-digital; art installation; art preservation; software maintenance; case study; portraits; pop-art; work in progress; interactionCitation: International Journal of Arts and Technology, Vol. 10, No. 3 (2017) pp. 206 - 230PubDate: 2017-09-18T23:20:50-05:00DOI: 10.1504/IJART.2017.086669Issue No:Vol. 10, No. 3 (2017)

Authors:Borut Batagelj, Franc SolinaPages: 231 - 240Abstract: Digital image analysis is a very useful tool to perform humanities studies on various art forms, not only because it allows us to precisely quantify various parameters relevant for humanities scholars, but also because it provides us with new insights and perspectives that are not readily available from traditional qualitative methods. In this paper we demonstrate the application of this method, where we use the mean grey values and the number of edge pixels to represent the level of brightness and the level of visual details in the images, respectively, to characterise and identify various interesting properties of the images found in <i>Tintin</i> comics. Our results also indicate that this method can be used to characterise and identify different comics artists based on the visual patterns in their works.Keywords: digital image analysis; comics; Tintin; greyvalues; edge pixelsCitation: International Journal of Arts and Technology, Vol. 10, No. 3 (2017) pp. 231 - 240PubDate: 2017-09-18T23:20:50-05:00DOI: 10.1504/IJART.2017.086675Issue No:Vol. 10, No. 3 (2017)
